SEAL-LOCK.

SPECIFICATION forming part of Letters Patent No. 359,450, dated March15, 1887.

Application filed No vcinbor 30, 1886.

To all whom it may concern:

Be it known that I, JAMES A. KI EY, residing at Chicago, in the countyof Cook and State of Illinois, and a citizen of the United States, haveinvented a new and useful Iniprovement in Seal-Locks, of which thefollowing is a full description, reference being had to the accompanyingdrawings, in which- Figure 1 is afront elevation showing thelock sealed;Fig. 2, a longitudinal section with the parts locked and sealed; Fig. 3,a front elevation Showing the lock open; Fig. 4, a longitudinal sectionwith the parts as shown in Fig. 3; Fig. 5, a cross-section through thehinged face-plate; Fig. 6, a detail of the sliding bolt; Fig. 7, abottom viewof a portion of the baseplate.

The object of this invention is to construct a lock to be used inconnection with a seal for the purpose of indicating any tampering withor opening of the lock, and thereby show whether the receptacle on whichthe lock is used has been opened; and its nature consists in the partsand combination of parts, hereinafter described and claimed as new.

In the drawings, A represents the hinged face-plate, formed, as shown,of a top piece, two side pieces, and an end piece, so as to leave anopen space, A,beneath the top piece.

B represents an opening formed in the top piece of the hinged face-plateA, and of dimensions to receive the seal, and have the edges of the sealprotected by the top plate.

0 represents the seal, made of glass or-other suitable material that canbe broken when desired, and, as shown, this sealenters grooves a in thetop of the hinged face-plate on each side, as shown in Fig. 5.

D represents a sliding bolt having on each side, at its rear end,projections c, to fit the grooves a, and having, as shown, a notch, d,to facilitate the withdrawal of the bolt after the seal has been broken.

E represents a staple having a slot, 6, for the.

passage of the sliding bolt D, and also, in the form of constructionshown, a hole, e, to receive the hasp of the ordinary padlock whenSerial No. 220,280. (Models) a hole, f, for the passage of a bolt,screw, or other device for attaching the lock to the receptacle.

G represents a spring secured to the baseplate A bya rivet, g, or'othersuitable means.

H represents a lockinglatch for the seal, havingat one end a lip, h, tobe engaged by the free end of the spring G when the latch is closed tohold the seal in place, and having at its other end an ear orfinger-piece,h,by which the latch is closed, and at this end, in theconstruction shown, is a shoulder to engage the end of the seal when thelatchis closed. This latch H is mounted on a pin or rod, t, between theside walls of the hinged face-plate, A, the ends of the pin or rodbeingriveted or otherwise firrnly secured in the side walls. The hingedface-plate A is attached to the baseplate F by the hinge-rod or pivot j,which passes through the side walls of the plate A, and through an caron the plate F, the ends of the hinge-rod or pivot j being riveted orotherwise firmly fastened in the side walls on the plate A. As shown,channels it are formed in the under face of the plate F for the escapeof fine or broken pieces of the seal, so that no interference with theoperation of the spring, latch, or hinged face-plate will occur fromthebroken particles, and in the construction shown a guide-arm, e, isformed on the plate F, to guide the hinged face-plate and also firmlylock against side play of such plate. The slots a do not extend the fulllength of the top of the hinged face-plate A, an end wall being left foreach slot, against which the projections a strike and limit the endmovement of the locking-bolt.

The spring G is attached to the base'plate F, to have its free endengage and lock the lip h of the latch H, and Said latch is attached tothe faceplate A by its pin or rod 2', and the hinged faceplate A isattached to the baseplate by its rod or pivot j, the sliding boltbeinginserted in place before the attachment of the latch, and when theparts are attached the lock is ready for use.

In use the base-plate F is secured at the.

proper point to the receptacle with which the lock is to be used to havethe hasp or other fastening device for the receptacle to pass over thestaple E, so that when the sliding bolt D engages said staple the haspor other locking means will be secured. The hinged face-plate, with theparts thereto attached, is raised, as shown in Figs. 3 and 4:, so thatthe hasp or other device can be placed over the staple E. The hingedface-plate is then thrown down and the sliding bolt passes into the slot6 in the staple E. The seal 0 is then inserted in the top of the plate Aand the latch thrown up to engage edge of the seal wit-h the face h, andhave the end It caught by the end of the spring G, which locks the latchin position, as shown in Fig. 2, and holds the sliding bolt D againstwithdrawal until the seal 0 is broken as the seal abuts against the endof the sliding bolt, and its other end is held against the face h of thelatch H. The sliding bolt D is withdrawn by breaking the seal 0, andthen raising the bolt from the end or through the notch d by means of aproper tool, or in any other suitable manner, and when withdrawn thehinged face-plate can then be raised, which unlocks the latch H from itsspring, and then the parts are ready for the next use, and it will thusbe seen that solong as the seal remains intact or unbroken the slidingbolt is held against withdrawal, so that in case i the seal is brokenthe breakage discloses that the lock has been tampered with and thereceptacle opened.

The lock is very simple in construction, is easily applied, and itsseveral parts coact one with another in the operations of locking andunlocking.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

l. The hinged face-plate A, a seal, and a sliding bolt carried thereby,in combination with the locking-latch for holding the bolt againstwithdrawal until the seal is broken, substantially as specified.

2. The combination, with the seal 0 and bolt D,of the hinged face-plateA, and locki ng-latch H,for engaging the edge ofthe seal and holding thebolt against withdrawal, substantially as and for the purposesspecified.

3. The hinged face-plate A, seal 0, and sliding bolt D, in combinationwith the staple 1G, baseplate F, spring G, and locking-latch H,substantially as and for thepurposes specified.
